IPC: G03F1/68
Filed: 1990-06-21
Abstract: PURPOSE:To obviate the misregistration of a mask by forming an aperture on a light shielding material layer, providing a resist layer thereon and subjecting the resist layer to back exposing and developing to obtain the pattern of a phase shift material, then patterning the light shielding material layer. CONSTITUTION:The resist layer 21 and the light shielding material layer 10b are formed on a transparent substrate 1 and are patterned to provide the aperture 3 in the part where the phase shift part is to be formed. The photoresist layer 2 is then formed in at least the part of the aperture 3 of the pattern 10b and is subjected to photoirradiation from the rear surface of the substrate 1 to expose the layer 2 with the pattern 10b as mask. This layer is developed to form the pattern 11a of the phase shift material. The pattern 10b is thereafter patterned to form the light shielding part 10 and the light transparent part 12.

Title: Color identifier for article
Inventor: FUKUMOTO YASUHIRO
IPC: G01J3/50
Filed: 1985-07-24
Abstract: PURPOSE:To reduce malfunctioning frequency in color identification, by correcting the amount of three color components of article on the basis of the results of detecting the amount of color components in the ambient environment thereof to detect the amount of color components of the article. CONSTITUTION:A signal of color components in the ambient environment of article is fetched from a color sensor 4 for ambience of article and the correction value based on the variation of a color identification signal is computed with a correction value computing circuit 11 in the ambient environment of article when a color identification is done for color teaching. On the other hand, a color component signal of article 1 is fetched from an article color sensor to be memorized with a memory circuit 7. At this stage, color component signal values of three colors of the article 1 differ by the amount corresponding to changes in the intensity of lumination and color components in the ambient environment of the article from those at the color teaching. But the color component signal values of three colors of the article 1 are addition corrected by the correction value with a color component arithmetic correction circuit 12 for article. Thus, the color component signal values of the article 1 roughly coincide with those at the color teaching thereby enabling accurate color decision.

Title: Pcm audio broadcast receiver
Inventor: OOMOTO NORIAKI
IPC: H04L27/14
Filed: 1990-06-21
Abstract: PURPOSE:To use a communication satellite(CS) receiver and an audio PCM broadcast receiver in common by applying peak detection to an input signal so as to output a control voltage controlling the gain of 1st and 2nd variable gain amplifiers. CONSTITUTION:First and 2nd variable gain amplifiers 103, 106 play the role of making an input level to a demodulator constant even when the input level of an inputted 1st intermediate frequency signal is changed. A peak detector 131 detects the peak level of an inputted signal and compares it with a reference voltage to generate the error signal to keep the input level constant. The signal is amplified to be the prescribed level of a control voltage and it controls the variable gain amplifiers 103, 106 thereby making the input level to an FM demodulator 132 constant and the input level to an MSK demodulator 108 constant simultaneously, then the AGC function to both demodulators 108, 132 is used in common. Thus, the function of the channel selection and the AGC function are used in common for the reception of an audio PCM broadcast and the reception of a video transmission.

IPC: C23C14/16
Filed: 1987-06-30
Abstract: PURPOSE:To provide a plated steel sheet with which sufficient weld strength and airtightness are obtainable under welding conditions of a wide range by forming the film consisting of an alloy of a metal which has the m.p. lower than the m.p. of steel and does not impair the corrosion resistance possessed by Cr and Cr on the steel sheet. CONSTITUTION:The film consisting of the alloy of the metal which is lower in the m.p. of the alloy with the Cr than the m.p. of the steel and does not impair the corrosion resistance possessed by the Cr and the Cr is formed on the surface of the steel sheet. The formation of the film is executed by a dry process of a vacuum deposition method, ion plating method, etc. Mn, Ni, Pd, Sb, Si, Ti, Zr, Al, Co, etc., are used as the metal element to be alloyed. The formed film forms an energizing path locally upon starting of energization at the time of electric resistance welding but melts soon, thereby shifting into the uniform energization state. Since the melting of the steel begins thereafter, a good nugget is formed and the dust to be generated by the local heating is eliminated.
